Sensor Locations? Where are these?
Im looking for on a 1993 WRX the locations of the sensors:
Knock Sensor,
Idle air control solenoid (Is this the one with the grey top, 2 screws either side and adjustbale?)
Throttle position sensor (Again on the inlet right next to the throttle?)
Oxygen Sensor (Lambda sensor isnt it?)
Idle Switch
Wastegate Control Solenoid Valve (Is this the 3 Port Solenoid?)
Pressure Sensor - Just to the side of the Boost Solenoid?
The car is running fine now, checked ECU codes and came up with this though still?
Boosting to 10.5 psi and everything seems fine. But ECU isnt getting these inputs.....
Any ideas?

Knock sensor - under the IC near throttle body just on the drivers side of the engine block. It looks similar to the bosch sensor.
Idle air control thingy - Yes, you're correct.
Oxygen sensor - Yes, right again.
Throttle position sensor - black matchbox sized thing on the throttle body.
Idle switch - built into the throttle position sensor. (4 pins - 2 for each function)
Wastegate solenoid - yes, correct.
Pressure sensor - the black thing next to the wastegate solenoid.
Are these historic codes? Do they come back after you reset the ECU?
And isn't standard boost 12 PSI, or is that only the later cars?

Dnb - Thanks for all your help once again mate.
Just going to reset the ECU now after checking all connections and trying again.
Only on the later cars. Early 1993 WRX were 240bhp.
